I've travelled in a Bell 47G as the THIRD person, hanging out on the
right-hand side (no door of course). It was in the Blue Mountains near
Sydney, on a pleasure flight en route to travel on the great zig zag
railway. http://www.zigzagrailway.com.au/

Been there, done that (the Great Zig-Zag, not the Bell). Perhaps the Bell
helicopter was designed by a descendant of the Bell of Bell's Line of
Road, by which we returned to Sydney.
